Description

Fremgangsmåte og anordning for sugetransport av avfall og lignende. Procedure and device for suction transport of waste and the like.

Det er kjent anlegg for sugetransport av avfall og lignende der avfallet gjc-nnom en rorledning ved hjelp av lurt utsatt for en trykkdifferanse transporteres fra en tilførselskilde, f.eks. en avfall ssjakt, til en oppsamlingsb>iholder eller silo i hvilken avfall 3t skilles fra transportlu H.en. Fr.. denne oppsamlingsbeholder uttas det oppsamlede av rall for a fores til et endelig avleveringssted, f.eks. en forbrenninjsanord-ning der avfallet forbrennes. There are known installations for the suction transport of waste and the like where the waste is transported from a supply source through a pipeline using a pipe exposed to a pressure difference, e.g. a waste chute, to a collection container or silo in which waste is separated from transport lu H.en. From this collection container, the collected is taken out of the rall to be taken to a final drop-off point, e.g. an incineration device where the waste is incinerated.

Det har ifolge oppfinnelsen vist seg å medfore store fordeler for dette formål å fore avfallet ut fra oppsamlingsbeholderen eller siloen i det vesentlige samtidig ved at det ved hjelp av sugeluften fores inn i beholderen eller siloen. Herved okes således den for sugetransport anvendelige tid, hvorved anlegget får bket kapasitet. Oppsamlingsbeholderen eller siloen kan videre gjores mindre og lavere enn ellers, hvorved anleggsomkostningene reduseres og transporthoyden blir mindre. Man får også stor mulighet for automatisering av tommingen av oppsamlingsbeholderen og videre-transportering av avfallet blir mer uavhengig av når selve sugetransporten skjer. According to the invention, it has been shown to bring great advantages for this purpose to feed the waste out of the collection container or silo essentially at the same time by feeding it into the container or silo with the help of the suction air. In this way, the time available for suction transport is increased, thereby increasing the plant's capacity. The collection container or silo can also be made smaller and lower than otherwise, whereby construction costs are reduced and the transport height is reduced. There is also great opportunity for automating the emptying of the collection container and onward transport of the waste becomes more independent of when the actual suction transport takes place.

Tomming av oppsamlingsbeholderen behover nodvendigvis ikke skje i samme takt som innfbringen av avfallet i denne. Emptying the collection container does not necessarily need to happen at the same rate as the introduction of the waste into it.

En anordning for utovelse av fremgangsmåten ifolge oppfinnelsen må være utfort slik at uttagningen av avfallet fra opp-saml ingsbeholderen skjer uten at nevneverdige mengder ytterluft får anledning til å lekke inn i beholderen, slik at det for transport av avfallet nodvendige undertrykk i denne vil gå tapt helt el]er delvis. Ifolge en spesielt hensiktsmessig utforelsesform ifolge oppfinnelsen komprimeres avfallet i for-bindelse med at det tas ut av oppsamlingsbeholderen, hvorved avfallet blir lettere å håndtere og opptar mindre volum for fortsatt behandling. A device for carrying out the method according to the invention must be designed so that the removal of the waste from the collection container takes place without significant amounts of outside air being allowed to leak into the container, so that the negative pressure required for transporting the waste in it will be lost wholly or partly. According to a particularly suitable embodiment according to the invention, the waste is compressed in connection with its removal from the collection container, whereby the waste becomes easier to handle and takes up less volume for further processing.

En utforelsesform av en anordning for utovelse av fremgangsmåten vises skjematisk på vedlagte tegning der fig. 1 er et sideriss og fig. 2 et planriss. An embodiment of a device for practicing the method is shown schematically in the attached drawing where fig. 1 is a side view and fig. 2 a floor plan.

På tegningen vises at siloen eller oppsamlingsbeholderen A er forbundet med en tilforselsledning G for avfall som ved sugetransport fores fra et hensiktsmessig innmatningssted. Det nodvendige undertrykk for transporten oppnås f.eks. ved en ledning H som munner ut i siloen, hvilken ledning står i for-bindelse med en hensiktsmessig undertrykkskilde f.eks. en sugepumpe. Ledningen G munner hensiktsmessig tangentialt ut The drawing shows that the silo or collection container A is connected to a supply line G for waste which is fed by suction transport from a suitable feeding point. The necessary negative pressure for the transport is achieved e.g. by a line H that opens into the silo, which line is connected to a suitable negative pressure source, e.g. a suction pump. The line G expediently exits tangentially

i siloen A, hvorved adskillelse av avfallet fra transportluften lettes, idet transportluft fores vekk gjennom ledningen H. in the silo A, whereby separation of the waste from the transport air is facilitated, as transport air is led away through the line H.

Det utskilte avfallet uttas fra siloen A omtrent samtidig som nytt avfall fores inn i denne. Dette skal skje uten at nevneverdige mengder ytterluft lekker inn i siloen. For dette formål kan det anvendes en anordning B, som omfatter et omtrent horisontalt hus med et deri anbragt stempel eller annet for-flytningsorgan, som skyver avfallet fra siloens A nedre del gjennom en ledning I i en til siloen A avtagbart tilkoblet og fra denne avstengbar beholder, f.eks. en vogn C for videre-transport f.eks. til et anlegg hvor avfallet forbrenner eller odelegges. The separated waste is removed from silo A at about the same time as new waste is fed into it. This must happen without significant amounts of outside air leaking into the silo. For this purpose, a device B can be used, which comprises an approximately horizontal housing with a piston or other moving device placed therein, which pushes the waste from the lower part of the silo A through a line I in a removably connected to the silo A and can be shut off from this container, e.g. a wagon C for onward transport, e.g. to a facility where the waste is incinerated or disposed of.

Ledningen I inneholder to avstengningsorgan D, E og et kob-lingsorgan F, som f.eks. kan være hydraulisk. Ved hjeLp av avstengningsorganet D kan siloen avstenges når anordningen B ikke arbeider, og ved hjelp av avstengningsorganet E som hensiktsmessig er anbragt på beholderen C, kan man hindre at det i denne innforte avfall tilsiktet forlater beholderen C. Når avstengningsorganet D er stengt, kan det av stemplet frem-skjovede avfall komprimeres og i denne tilstand fores inn i beholderen C eller lastes direkte på en eller annen hensiktsmessig anordning. Når organet D er stengt, kan beholderen C utbyttes uten at sugetransporten avbrytes, hvorfor anordningen tjener som en slags sluse. The line I contains two shut-off means D, E and a connecting means F, which e.g. can be hydraulic. With the help of the shut-off device D, the silo can be shut off when the device B is not working, and with the help of the shut-off device E, which is appropriately placed on the container C, it is possible to prevent the waste introduced in it from intentionally leaving the container C. When the shut-off device D is closed, it can waste pushed forward by the piston is compressed and in this state fed into the container C or loaded directly onto some other appropriate device. When the device D is closed, the container C can be replaced without interrupting the suction transport, which is why the device serves as a kind of lock.

Det kan anordnes en indikeringsanordning som trer i funksjon når beholderen C er full og skal skiftes. Dette kan eventu-elt skje automatisk ved en impuls fra indikeringsanordningen. Koblingsorganet F sammenkobler lostagbart siloen A og vognen C. Komprimeringen skjer hensiktsmessig i vognen C. An indicating device can be provided which comes into operation when the container C is full and needs to be changed. This can possibly happen automatically by an impulse from the indicating device. The coupling element F removably connects the silo A and the wagon C. The compaction takes place appropriately in the wagon C.
